Terms | Definitions |
|---|---|
 Newton's First Law | an object at rest will stay at rest, an object that is moving will stay moving unless disturbed by an un balenced force. |
| Newton's Second Law | the net force of an object is equal to the product of it's acceleration and mass. |
| Newton's Third Law | for every action there is an equal and opposite reaction |
| Acceleration on the Sun | 274 m/s squared |
| Acceleration on Earth | 9.8 m/s squared |
| Mass | how much matter that an object takes up |
| Weight | how much earth's gravity pulls on you |
| how does a photogate work? | it measures the time by detecting the blocking or unblocking of a beam of light |
| in order for something to have a balanced force | it is either standing still or moving in a straight line at a constant speed |
| Pseudoscience | a belief or practice that is claimed to be scientific, but which does not adhere to an appropriate scientific methodology, lacks supporting evidence or plausibility, or otherwise lacks scientific status. |
| Fn | Normal Force |
| Gallileo did what? | Built a telescope and used it to discover the mountains on the moon and the moons of Jupiter |
